As a result of the unique resin coating technology of ICL Specialty Fertilizers, Osmocote Bloom for bedding plants has a very regular release pattern. Osmocote Bloom is especially suitable for use in short bedding plants cultures from 6 weeks up to 3 months. For other bedding plant types we recommend using Osmocote Exact Standard High K 3-4M or 5-6M.

The longevity of Osmocote Bloom is affected by temperature (product longevity is determined at 21ºC).

Recommended Rates

 Target Crop Light feeding Normal feeding Heavy feeding
Plants / Annuals 1.5-2 g/l 2-3 g/l 3-4.5 g/l

The above mentioned recommended rates are based on non fertilized substrates. The optimum results can be reached when the potting soil does not contain starter fertilizer. However, if a starter fertilizer is used we recommend using not more than 0,5 kg/m3 in combination with the above mentioned application rates. Osmocote Bloom is primarily meant for mixing into growing media – we do not recommend this product when dibbling. Re-fertilization with water solubles and/or adjustments for water quality can be required in specific circumstances. Contact your ICL Specialty Fertilizers advisor for more detailed advice.

Trial first on a small scale before rate, application or other changes in your cultural practices are implemented. As circumstances can differ and as the application of our products is beyond our control, ICL Specialty Fertilizers cannot be made responsible for any negative results.
